Cresol Red Indicator Extra Pure

SHORT DESCRIPTION Cresol Red Indicator Extra Pure is a high-purity pH indicator dye widely used in laboratory titrations, buffer solutions, and biochemical assays. It exhibits a clear color change from yellow to red over the pH range of approximately 7.2 to 8.8, making it suitable for detecting slight pH shifts in weakly basic environments. Its stable performance and extra pure grade ensure consistent results in analytical chemistry, molecular biology, and spectrophotometric applications. Ideal for use in precise pH monitoring, Cresol Red should be handled with care and stored away from light and moisture to preserve its integrity.

Eriochrome Extra Pure

SHORT DESCRIPTION Eriochrome Extra Pure—typically referring to Eriochrome Black T—is a complexometric indicator primarily used in EDTA titrations to detect metal ions, especially calcium (Ca²⁺) and magnesium (Mg²⁺) in water hardness analysis. In its extra pure grade, this dye ensures sharp, precise endpoint detection by minimizing impurities that could cause background coloration or interferences in spectrophotometric or volumetric determinations. It functions by forming a wine-red complex with metal ions, which turns blue when the metal is sequestered by EDTA. Suitable for high-precision analytical chemistry, it should be stored away from light and moisture to preserve stability.

Hydrogen Peroxide Extra Pure

SHORT DESCRIPTION Hydrogen Peroxide Extra Pure is a clear, colorless liquid widely used as a strong oxidizing agent in laboratory and industrial settings. This high-purity grade ensures minimal contamination, making it ideal for analytical chemistry, disinfection, bleaching, and redox reactions. In research labs, it serves as a reliable reagent for oxidation processes and sterilization. Its extra pure formulation enhances consistency and accuracy in sensitive procedures. Due to its reactive and potentially unstable nature, it should be stored in cool, dark conditions in vented containers and handled with appropriate protective equipment.

Iodised Salt Extra Pure

SHORT DESCRIPTION Iodised Salt Extra Pure is a refined form of sodium chloride enriched with a precise amount of iodine, typically in the form of potassium iodate or iodide. It is primarily used to prevent iodine deficiency disorders, making it essential in nutritional and public health applications. Beyond its dietary use, iodised salt also serves in laboratory settings for controlled experiments involving iodine content and salt solubility studies. Its high purity ensures minimal contamination, making it suitable for analytical and pharmaceutical applications where quality and consistency are critical. Proper storage in airtight containers is recommended to prevent iodine loss due to air exposure.

Lead Acetate Extra Pure

Lead Acetate Extra Pure is a crystalline compound with the chemical formula Pb(C₂H₃O₂)₂·3H₂O, often referred to as sugar of lead due to its sweet taste (though it is highly toxic). In laboratory environments, it is primarily used for analytical chemistry, precipitation reactions, and as a reagent for detecting hydrogen sulfide gas, with which it forms black lead sulfide. It is also utilized in organic synthesis and historical pigment studies. Due to its toxicity, handling requires strict safety measures, including gloves, goggles, and proper ventilation. Its extra pure grade ensures minimal contaminants, making it suitable for precise experimental procedures.
